SEAL-LOC K.

To all whom it may concern,.-

Be it known that I, WILLIAM Lian GALLUP, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey, in the State of Minnesota, have invented certain new and useful Improvements in Seal-Locks, of which the following. specification is a full, clear, and exact description, reference being also had to the accompanying drawings, in which# Figure 1 is a front view, and Fig. 2 is aplan view, of sections of a car-door and its frame, showing one of my improved seal-locks attached thereto. Fig. 3 is a sectional view on thelinexxofFig.1,showingthelock sealed/7 and Fig. 4 is a similar view showing the lool; unsealed. Fig. 5 is a detached perspective view of one ofthe glass seals.77 Fig. 6 is a Fig. 7 is a similar view ofthe loeking-bolt, and Fig. 8 is a similar view of the locking-cani. Fig. 9 is a perspective view of the hasp or locking bar, and Fig. 10 is a perspective view of the slotted staple or socket. Figs. 11, v12, and 13 are views similar t0 Figs. 1, 2, and 3, showing a slight variation in the manner of holding the locking hasp or bolt in the lock. Fig. 14 is a perspective view of the loelceasing. Figs. 15 and 16 are perspective views of the locking bars or plates, and Fig. 17 is a perspective view of one end of the hasp or bolt as used in the modification shown in Figs. 11, 12, and 13.

rlhis device will be used generally in locking and sealing 7 the doors of freight-ears, but may be used in other places, if desired.

A is the casing or frame containing the locking mechanism, which will usually be attached to the casing B against which the ear-door C abuts, but may be attached to the door itself,

if preferred.

Dis a hasp-plate attached 'horizontally to the easing B above the frame A, and having ears a ai upon'its ends in which a hasp or U- shaped bar, F, is pivoted and adapted, when turned down, as shown in Figs. 1, 2, and 8, to fit into open slots Z) across the lower part of the frame A. rlhe pivot of the hasp E, next to the edge ofthe door C, is extended beyond the ear ai and formed into an enlarged flattened head, E2, at right angles to the hasp E, said head being adapted, vwhen the hasp is turned outward at right angles to the casing B, to pass through a perpendicular slot, c, in a staple or socket, F, attached to the door C. Vhen the door C is to be closed the hasp E is turned outward, as shown in Figs. 4 and 9, which will enable the head E2 to pass through the slot c, and then when the hasp is turned down again, as shown in Figs. 1, 2, and 3, the head Ez will also be turned down across the slot c and prevent the door from being opened until the hasp is again raised up. The front face of the vframe A slopes backward from above the center, leaving the lower half projeeting somewhat, so that small l upright grooves (7, (l2 maybe formed in the sides ofthe casing to receive a glass plate, G, as shown in Figs. 1, 2, 3, 4t, G, 11, 12, 13, and 14.. The slots b will be deep eno-ugh to enable the hasp E to enter deeply enough into the frame A to permit this glass plate G to be dropped down in front ofthe hasp, as shown in Figs. 1, 2, and 8, so that the hasp cannot be removed without removing the glass.

About opposite the rea-r of the upper edge ofthe glass plate G is pivoted, in the sides of the frame A, a cam-roller, H, formed with a flat rear side, e, and a notched front edge, @2, the said notched edge adapted to iit over the upper edge ofthe glass plate G, when the Hat rear side, e',is in an upright position,a s shown in Fig.

I is a bolt or stop sliding up and down in the rear of the roller H, in ways g g2 on the inside of the casing A, and adapted to slip down behind the flat side e of the roller H, when the latter is turned with its notched side e2 resting on the glass G, as shown in Fig. 3.

` The part of the cam-roller I-I between the notch ci andlat side c, is farther from the center of the roller than the notch er hat side, so that when the bolt I is raised up and the roller turned back, the latter will i'orin a stop to hold the bolt elevated, as shown in Fig. 4.

In Fig. 4. the lock and hasp are shown ready to be connectefhwhich is done (after the staple F is properly set over the head E?, as before deseribeth) by lowering the hasp E downinto the slots b, and dropping the glassG downinto the grooves d di. llhe roller H is then turned down by means of a knob, 71 on one ofits pivots, which will cause the notched side c2 to rest upon the upper edge ofthe glass G and bring IOO the flat side e' in an upright position and permit the bolt I to drop down behind it,as shown in Fig. 3. By this means the hasp is securely held in the frame A, and cannot be vremoved 5 unless the glass G be broken and the bolt I elevated above the roller H. rlhe casing Ais so constructed that the bolt I can only be reached through that part of the front of the casing A covered by the glass G, and as the 1o latter is held down by the roller H, the only access to the bolt is by breaking the glass, which is the end sought by this invention.

In Figs. 11, 12, and 13 a slight modification is shown, consisting in attaching the frame A I 5 to the door and the hasp E to the casing, or vice versa, and elevating the hasp E and passing the head E2 through an upright slot, t', in the side of the casing A, and turning the hasp down again to lock them together. 2o The glass plate is then droppeddown in front of the head E?, as in Figs. 11, 12, and 13. A bolt or pin, K, will be arranged to be dropped down through a slot in the head E2 and the roller H adapted to hold both this pin and the glass G down in place. A sliding plate,

M, may be used in place of the roller H, if preferred, said plate adapted to hold both the glass G and pin K down in place, and be held outward by the bolt I dropping down behind 3o it. This plate M will also be arranged, when pushed backward, to hold the bolt I elevated similar to the roller H in Fig. 4. The pin K may be dispensed with, and the head E2 held from turning by the plate M. By this arrangement, after the cars are once sealed and the record made, the person or persons having them in charge can ascertain at a glance Whether they have been tampered with or not, and-by noting the condition of the seals at lo designated' stations if an unlawful opening of the cars occurs the place can be promptly and accurately located, and the responsibility placed upon the proper person or agent. The

glass seals will be suitably marked, either by blowing into them,when manufactured, the initials of the railroad company owning the cars, or some lmark denoting the contents or ownership of the goods in the car; or a slip of paper with the proper Writing upon it 5o may be pasted upon the rear surface of the Yglass before it is inserted into the frame; or

In Figs. 1, 2, 8, 4, and 7 the bolt I is shown the full width of the inside of the casing A, and in Figs. 11, 12, 13, and'16 it is 'shown of a less width; but the operati on is substantially the same in both forms.

Springs may be used in place of the bolt l under some circumstances, but the results and action would be the same.

I do not Wish to confine myself to the form of hasp shown. Neither do I wishto be confined to the use of the head E2, as I am aware that many other suitable means may be used to accomplish the same result.

Some other substance than glass might be used for the plates G; but'I prefer glass as possessing peculiarly advantageous qualities for the purpose.

Having described my invention and set forth its merits, what I claim is- 1. In a seal-lock, the combinationof a case attached to a door or casing, a swinging hasp or bolt adapted to be held in the case by a sealplate, and provided with alockiug-head, the door or casing provided with a staple,in which the locking-head turns for locking the door, a glass seal-plate closing the open side o1' the sealing ease around the hasp or bolt, 'and means, substantially as described, for locking the said plate in the case, inaccessible for unlocking except by breaking the seal-plate, sub stantially as and for the purpose herein specified.

2. The combination of the sealingcase A, attached to the casing B, door C, provided with the staple F, hasp E, provided with the locking-head El, glass seal-plate G, eccentric roller H, and sliding-bolt I inside of the sealing-case, substantially as and for the purpose herein specified.

In testimony whereof I have hereunto set my handin presence of two subscribing Witnesses.
